Specification of Letters Patent.

Patented Sept. 59, 1913.

Application filed April 27, 1912. seriaino. 693,877.

To all whom it may concern Be itknown that I, DE YVITT C. BAILEY, acitizen of the United States, residing at Nichols, in the county ofPolk, State of Florida, have invented certain new and usefulImprovements in Pipe-Couplings; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention is directed to improvements in pipe couplings and has forits object to construct a coupling of this type which may be easily andquickly coupled or uncoupled.

A further object of the invention is to provide a ring for coupling theends of pipes so formed that the ring may be re moved from any point ina pipe line.

With these and other objects in view, this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawing, in which Figure 1 is anelevation of the device showing a pair of pipe sections coupled. Fig. 2is a sectional view on line 22 of Fig. 1. Fig. 3 is a sectional view online 3-3 of Fig. 2. Fig. 4; is an elevation of one of the pipe sections.Fig. 5 is a vertical sectional view through the ring. Fig. 6 is asectional view on line 66 of Fig. 2.

Referring to the drawing, the numerals 1 and 2 designate the pipes to becoupled, both of which are provided with flanged ends 3 and 4, theformer having formed upon its periphery a plurality of spaced lugs 5,the outer edges of which are inclined as at 6.

To hold the pipe sections in their coupled positions, a ring 7 isprovided, the inner face of which is formed with a plurality of lugs S.The lugs 8 are each provided with inclined edges 9, the purpose of whichwill appear later. The ring 7 has also formed on its inner face, andspaced from the lugs 8 a plurality of elongated projections 10, thenumber of projections being governed by the number of lugs 8.

Each projection is formed with a shoulder 11 against which the flangedend 4 of the pipe section 2 bears, said pipe section being held inclamped position when the lugs 5 formed on the flanged end 3 of the theinclined edges of the lugs 5 will engage the similar edge of the lug 8,said lugs 5 being guided in binding engagement with the lug 8 andprojection 10 through the space 12 formed therebetween, and thuslimiting the turning movement of the ring in one direction.

Set screws 13 are passed through the ring and have their inner endsadapted to en gage the periphery of the flanged end 4: of the pipesection 2, thus holding the said ring and pipe section in fixedrelation.

T o prevent accidental turning of the pipe section 1 a set screw 14: ispassed through the ring 7, and is of sufficient length to have its innerend bear against the flanged end 3 of the pipe section 1, and at a pointbetween the lugs 5 formed thereon, thereby holding said parts in fixedrelation.

From this construction it will be seen that should the ring 7 becomebroken from any cause whatsoever the same may be easily removed and anew one substituted therefor, as the construction of the ring is suchthat the same may be tilted to permit the flanged end 4 of the pipesection 52 to pass freely at points between the projections 10 either toremove a ring or substitute a new one. Thus it will be seen that thepipe sections may be coupled or uncoupled at any point in the pipe line,and that the rings may be interchanged if the occasion should requirewithout uncoupling more than a pair of the pipe sections;

hat is claimed is 1. In a pipe coupling, the combination with theabutting flanged ends of a pair of pipe sections, inclined lugs carriedby one of the flanged ends, a ring having inclined lugs formedinteriorly thereof, projections carried by the interior of the ring andhaving shoulders formed throughout their length, said shoulders beingadapted to engage one of the flanged ends of one of the sections toprevent removal of the ring therefrom in one direction, said projectionsbeing spaced from the lugs carried by the ring, the first named lugsbeing adapted to engage in the space between the lugs and projections tolimit the turning movement of the ring in relation to the pipe sections,and means passable through the ring to engage the pipe sections toprevent independent rotation of the pipe sections and ring.

2. In a pipe coupling, the combination With the abutting flanged ends ofa pair of pipe sections, inclined lugs carried by one of the flangedends, a ring having inclined lugs formed intei'iorly thereof,projections carried by the interior of the ring and having shouldersformed throughout their length, said shoulders being adapted to engageone of the flanged ends of one of the sections to prevent removal of thering therefrom in one direction, said projections being spaced Copies ofthis patent may be obtained for five cents each, by addressing theCommissioner of Patents,

from the lugs carried by the ring, the first named lugs being adapted toengage in the space between the lugs and projections to limit theturning movement of the ring in 15 Washington, D. G.
